Hi, I am 12 weeks pregnant today and my dating scan flagged up a NT reading of 4.1mm and the blood test came back today as higher risk with a 1 in 5 chance for Down Syndrome, my hcg reading is 0.68, has anyone had this before and it’s turned out to be nothing? It has taken 2 years to get pregnant, I am 41 and my husband is 43 so our age is against us. Can’t help thinking the worst. Had NIPT today and have to wait another week for results.
